To all whom it may concern:

Be it known that ORRELL ASHTON, late of Swampscott, in the county ofEssex and State of Massachusetts, deceased, invented certainImprovements in Assembling-Machines, of which the following description,

in connection with the accom anying draw-1 ings, is a specification,like re erence characters onthe drawings indicating like parts in theseveral figures.

This invention relates to machines for assembling parts of boots andshoes upon their lasts preliminary to the pulling-over and lastingoperations. For the purpose of illustration an embodiment of theinvention has been selected and is shown herein as applied to a machineof the type described 1n Letters Patent of the United States, No.1,204,928, granted November 14, 1916, upon an application of OrrellAshton.

It is'to be understood, however, invention is'not restricted toembodiment in a machine of the particular type disclosed in said atent.In the earlier machine above referre to the-upper is held to the last ata point adjacent to the heel seat and the upper is wiped downwardly ortoward the narrow top part or cone of theinverted last as well as overthe heel seat of the last, two tacks being then partially driven into-the\rearend face of the shoe and a single tack completely driven intothe end of the heel seat of the last through the upper material in endface of the cone of the last and then tensioning the uppertoward andover the heel seat of the last and there securing the upper materialsincluding the counter to the heel seat; Preferably the u per is alsosecured to the rear end face 0 the heel seatat a point near the heelseat.

A feature of the invention consists, there-, i ore, in means for holdingthe upper materials against the rear end face of the last at a pointremote from the last bottom, means of the cone that the grippingsurfaces Specification 011.6%! 2mm. 'r t t 'o t, 2 9 Application filedApril 17, 1618. Serial 110. 91,672.

for tensioning the-portion of upper 1 ing and preferably to the heelseat of the last. In the construction shown herein the last is bottom upand the upper is held clamped unyleldingly at a point adjacent to thetop part of the last between the last which is pressed inwardly-and ablock, referably V'-shaped, which is held in fixed position. Thisclamping means may be reliedupon to hold the upper at this point fromupward movement relatively to'the last, Tacking means, however,isprovided for o tional use which will insert a tack, preferab y throughV to the last, the block being arranged by verthe V-block, additionallyto secure the upper v through the upper and counter near the edge of thecounter which lies nearest the cone of the last. The upper while held atthis pressure of the last against the point, by

also by the tack if desired, is tenblock and sioned upwardly by thetensioning means which, as shown herein, comprises the forward end ofthewiper and a cooperating gripper member which is actuated to grip theupper'between it and the end of the wiper. The wiper is operated in adirection to wipe theupper over upon the heel seat, at the same timeacting to tension the upper throughout substantially the full width ofthevamp in an upward direction from a point near the top of the cone ofthe last where it is held bythe clamping pressure as described and ifdesired also by the tack already driven at'that point. As the wiperadvances the upper, preferably, is gradually withdrawn from between thecooperating of the wiper and gripper member and is laid under tensionupon the heel seat, means being provided for securing the uppermaterials including the counter thus treated to the heel seat. Thismeans as shown comprises tacking mechanism which acts preferably throughthe wiper to insert a tack at the rear end of the heel seat through theoverlaid margin of the'counter," and to clench itupon the heel plate ofthe last.

lining and innersole V-block and acts to center The means for clampingthe upper 11nyieldingly against the cone of the last may comprise, asshown, a last support WhlCh forces the last rearwardly against the fixedlower V-block and holds the upper clamped at this point during theupward tensioning of the upper. Preferably also, the last support isheld against downward movement during the overwiping movement of thewiper.

It is important that the shoe support, during the positioning movementof the shoe relatively to the upper tensioning means, he movablevertically to facilitate insertion of the upwardly extending margin ofthe upper between the gripping members. A feature of the invention,therefore, consists in the combination with tensioning means to whichthe upper is presented by upward movement of the shoe, of means forsupporting the last for depression by light downward pressure andsadapted when the last is released to raise the last and bring the upperinto position between the gripping members and the tensioning means.

Another feature of the invention consists in the combination with meansfor holding the upper unyieldingly at the rear of the last near the coneof the last, and means for tensioning the upper upwardly from the pointheld, of means for pressing yieldingly against the rear end face of thelast at a point adjacent to the heel seat; Means is also provided whichmay be used when desired for securing the upper to the last at thispoint by a partially driven tack. As shown, the yielding pressing meanscomprises a second block which is preferably a the last by engagement ofits inclined faces with the curved rear face of the last. This block ismounted for yielding movement rearwardly in a substantially horizontaldirection, being preferably held forward by a spring in a position inadvance of the lower V- block so as to engage the shoe first as the shoeis moved toward the machine and to press the shoe parts into assembledrela-' tion on the last. As shown tacking mechanism is provided whichmay or may not be used at the option of the operator to insert a tackpreferably through the block and into the-rear end face of the shoe atone side of the back seam and near the plane of the heel seat.

In lasting the sides of shoes the side laster is required to see thatthe ends or wings of the counter stiffener are properly -drawn up at theshank of the shoe and secured to the tread face of the shank of thesole. Under some-conditions, particularly where molded counters areused, it is also demanded of the side laster that he secure to the heelseat the flange of the counter which extends over the heel seatwhich atthe rear of the shoe by tacks driven not through the upper but throughthe counter flange and into the heel seat at each side of the tackdriven by the assembling machine through the upper and counter flange atthe rear portion of the heel seat adjacent to its longitudinal medianline. Since the rear portion of the upper is held by this central tackin a position bent over the rear portion of the counter it is only withsome difficulty that the laster can insert tacks at each side of thecentral tack through the flange of the stifi'ener only and thisrequirement. reduces his production.

An important feature of this invention consists in means forinsertingtacks through the flange of the counter-or heel stiffenerautomatically and as a part of the assembling operation. By this meanstacks are driven near the rear end of the heel seat through the flangeof the counter stiffener and into the heel seat. As shown herein theflange tack driving mechanisms operate substantially simultaneously withthe means for driving the central tack at the rear end of the heel seatand are located ads jacent to what are known as the corners of the heelseat, that is, near the points where the curvature of the rear end ofthe heel seat merges into the curvature at the side of the heel seat.These flange tacks, therefore, are located at each side of the centraltack at the end of the heel seat and somewhat in advance of it or nearerthe toe of the shoe. The central tack at the end of the heel seat,herein termed the through the upper as well as through the counterlining and innersole, and the tacks in advance of it, termed herein theflange tacks, are not driven through the upper but through the flange ofthe counter stiffener, lining and innersole only, all of these tacksbeing clenched upon the heel seat plate of the last. Preferably twoflange tacks are driven, one. at each side of the heel seat tack and inlaterally and forwardly spaced relation from it.

heel seat tack, is driven.

Another feature of the invention consists tively the counter, upper, andlast.' The counter pressing means may include pressers hold in thecounter at the wings of the counter and preferably and as shown thecorner and wing pressers are so connected to their operating means thatthe pressure is distributed between them and preferably seen that thelipper and lining and innersole assembled thereon, inserts acounter, forexample, amolded counter between the upper and lining, and places thelast upon the spindle 20. He then depresses the spindle against thespring 18 and swings it toward-the machine. Having swung the shoeinwardly as far as it will go, he releases it and allows the post 16 torise under the impulse of spring 18. This movement brings the upper atthe rear of the shoe into the position shown in Fig. 7, the upwardlyextending margin of the upper then lying between the nose of a wiper anda gri per member 72 having a gripping face of a curvature correspondingto that of the nose of the wiper and adapted when operated to hold theupper against the nose of the wiper as illustrated in Fig. 8. When thework has been positioned as described the operator depresses a treadle76, Fig. 1, which acts through a rod 78, Fig. 2, upon a controllingmechanism 79 to connect the shaft 6 with the power driven pulley 80. Thecontrolling mechanism 79 may be of any usual type but as herein shown issubstantially similar to that disclosed in United States Letters PatentNo. 1,026,067, granted May 14, 1912, on application of Orrell Ashton. Asthe cam shaft 6 begins to rotate, the projection on the cam 42 passesbeyond the roll 40 and permits the spring 44 forcibly to depress thehook 30 which acts upon the roll 50 to draw the jack and shoe inwardlytoward the machine and lock it inwardly and against depression asdescribed. As the shoe is drawn in toward the machine it first contactswith an upper V-block 86, Fig. 8. This block is mounted on a horizontalslide to yield inwardlyagainst a spring 88, Fig. 1, and by yieldingallows the shoe to come into engagement with a lower V-block 90 whichisheld in fixed position. The shoe is now held with the upper andcounter firmly pressed against the rear end face of the last, the upperbeing held unyieldingly near the cone of the last at each side of theback seam by pressure of the last against the V-block 90 due to theaction of the cam face of the hook 30 upon the last support and beingheld yieldingly near the heel seat by pressure of the V-block 86. Theupwardly projecting portion of the upper has been seized between thenose 70 and the gripper 72 by mechanism actuated simultaneously' withthe downwa-rd movement of the hook 30 in the following manner.

Referring to Figs. 3, 4 and 6, it will be the hook 30 when in its normalposition with the machine stopped engages a roll 100 on the end of alever 102 which is pivoted at 104 to a bracket 105 mounted on the base2. The lever v102 has a projection on its upper face which enga es anarm 106 fixed to a rock shaft 108 aving 150 are pivoted. for limitedalso a longer arm 110. The rock shaft 108 tends to rotate in a directionto depres the outer ends of the arms 106,110 b reason of a spring 111,Fi 3, coiled a out the shaft 108, one end 0 which engages a lug 113 onthe bracket105, the other end of the spring being secured to a collar115 which is held to the shaft 108 by means of a ratchet and pawlmechanism which affords means for adjusting the tensionnof the spring111. A pull rod 112 passes through a trunnion 114 journaled in the outerend of the arm 110and is connected at its upper end to one arm 116 of abellcrank lever, the other arm 118 of which is connected b a link 120toa rod 122 one end of which is rigidly secured to the gripper 72 belowits pivot 124. The rod 112 carries below the trunnion 114, an adjustablyfixed collar 126, and above the trunnion a sliding collar 128 which isbacked by a light spring 130 held by its upper end to a fixed collar132. Referring now particularly to Fig. 6, it will be seen that when thehook 30 is depressed as described the pressure of the projection on thelever 102 against the arm 106 will be released, permitting the spring111 to act upon the rock. shaft 108 and depress the outer end of the arm110. This arm acting upon the collar 126 moves downwardly the rod 112and through the bell-crank lever .116, 118 pul1s upon the link 120 toforce the gripper member 72 into position to hold the upper be tween itslower end and the nose 70 of the wiper. When the arm 110 is again raisedat the end of the cycle of the machine the spring 130 will yield ifnecessary points prevents the counterfrom bulging or drawing away fromthe last. This mechanism is actuated simultaneously with the operationof the gripper 72and comprises mechanism best shown in Fig. 3. clampingmembers 150 are located one upon each side of the shoe and each carriestwo upper clamping projections 152, 154 which are inclined upwardly andinwardly to- Ward the shoe and engage the sides of the shoe insubstantiall the planeof the heel seat as shown-in ig. 14, theprojections 154 engaging the sh e at the corners of the heel seat andthe projections 152 pressing in the wings of the counter.

Referring to "Fig. 1 of the drawing, the

numeral 2 indicates the base or column of the machine and 4 the frame ofthe head of the machine upon which various operating parts of themachine are mounted and are operated by cams or other mechanism con- 7nected with the main shaft 6. A jack memher 8 is pivoted at 9 totheframe of the machine and has its outward movement limited by a rod 10carrying a bufier-sprin 12. A red 14 telesco es into the lower en 16, te jack post 16 being supported upon the rod 14 by a spring 18. The.rod'14 is reduced at its lower end to e age a hole in a piece 15 whichis adjustal fy held in the member 8 by a set screw 17. In the upper-endof the post 16 a last in 20. is fitted which may be adjusted vertica yrelatively. to the post 16 by lifting and rotat of a jack post igs. 4and 5 are sectional details of a ing the pin to cause a proje'etion 22to engage in one of a series of vertically spaced,-

notches 24 formed around theperiphe of the upper end-of the hollow post16. lhe stren h of the 5 ring is such that the post may depresse by theoperator, its movement being suitably limited by a pin and slotconnection between the parts 14 16 at 19 and mechanism is provided forforcing and holdin the 0st in toward the machine and for 100 g t againstdepression while the machine is inoperation. This mechamsm comprises ahook 30 pivoted at 32 to the machine frame and arranged tov be operatedby a rod 34 which connects a rearward .-.extens1on of the hook 30 with abell-crank acted upon by a cam 42 fixed upon the shaft 6. p The actionof the cam upon the cam roll 40 raises the hook into the osition shownagainst a stiif spring 44 coiled about the axis 32 and arranged forciblyto depress the hook 30 when the rojection on the cam 42 moves off theroll When the post is swung-toward the machine about the pivot 9, a roll50' mounted on the member 8 is brought into position to be engaged bythe hook 30 when it is de ressed, as described, the hook thereby lockingthe shoe support inwardly toward the machine during its operation. Theface of the hook 30 which engagesthe roll 50 is not concentric with thepivot 32 but is cam-shaped to force the roll and support inwardly as thehook is moved downwardly.

The hook 30 also effects a locking of the post 16 against depression, asshown in Fig. 5. The post 16 has formed upon it a series .of ratchetteeth 52 and passes loosely through an opening 53 in 'a'member 54 whichis pivoted at 56 to the member 8. The member 54 carries a locking pawl58 which is arranged to enga e the teeth 52 when the member 54 is moveto the left in Fig. 5 by the action of the hook 30 upon the roll 50provided the. 0st 16 is prevented from moving inwar 1y by reason ofcontact of the work with. arts of the machine. When movement 0 the post16 toward the machine is thus prevented the lower part of the member 54where the post passes through the hole 53, ,is, of course, preventedfrom moving inwardly and the member 54, being held at 53, swings aboutthe pivot 56 causing a rojection 60 upon the member 54 to ress ownwardlyupon a spring plunger 62.

hismovement allows the pawl 58 to come in contact with the ratchet teeth52 and to lock the post 16 against depression. When .the hook 30 israised the spring plunger 62 acts to release the locking pawl from theratchet teeth and the post 16 is free to move vertically.

The ma safts 160 extend'downwardly and carry at their lower ends-inwardlyprojecting arms 164. Coiled torsion springs 166 are connected betweenthe,'bracket 105 and fixed collars 167 on the rock shafts 160 so as tocause the arms 158 to move toward each other thereby bringmg-theprojections 152, 154-on the levers of the shoe.

work simultaneously with the operation of the ipper member'72 to seizethe upper.

T e upper is now correctly positioned and held for the insertion of thefirst fastening which is inserted through the lower V-block 90, asshown-in Fig. 8. The tack for the block 90 is en plied by a tackseparator located at 170, i 1, and passes through a driver passage inthe block 90 in front of a driver. mounted on a driver bar 174 which isactuated by alever 176 piv-' oted at 178 and having a projection 180scribed in .thepatent construction in detail.-

which engages a cam 182 on the main shaft. The drop of the cam is soarranged as to actuate this driver by its driver spring mounted upon theshaft 178 prior to the actuation of the other tack drivers. and prior tothe forward reciprocation of the wiper which next takes place. f

The wiper 70 is mounted and operated in a manner substantiall as isshown and dest referred to above. It is therefore not necessa' todescribe this hewiper 70 'is moved forwardlyover and along the meearupon the shoe and a hen the machine is in stopped by the action of the.

gripper member 72 holds the upper against the end of the wiper 70 andcooperates therewith.to tension upwardly at the rear of the shoe theportion of the upper which. extends above the tack alread driven throughthe block 90. At this point the upper is held by said tack and by thepressure of the shoe against the rigidly held block 90 While the upperblock 86 is held ieldingly against the upper and permits the upper todraw upwardly beneath it as the wiper and gripper member advance totension the upper over the shoe bottom. uring this move- -ment theportion of tween the nose of the wiper and the gripper member isgradually withdrawn from engagement between them. While held'undertension by the frictional engagement of these members, however, it islaid down upon the shoe bottom and is held in that position by pressureof the wiper on the shoe bottom until it is secured by a tack driventhrough the upper held be-i the wiper 7 O and into and through the.overlaid upper, counter, lining and innersole and clenched upon theheel plate of the last, as is clearly shown in Fig. 9.

The wiper 7 0 moves a predetermined distance over the shoe bottom andhence the heel seat tack is driven at a predetermined distance .from therear edge of the bottom of a shoe positioned by the block 90. Thisdistance may be varied by turning the hand wheel 85, the constructionfor efiecting this adjustment being substantially the same as that shownand described in the prior patent first referred to above. I

The wiper 70 is let into the upper facev of the block 86 by a groove 71,Fig. 3. This construction permits the upper block 86 and its tackingmechanism to be adjusted near to the plane of the heel seat.

Substantially simultaneously with the insertion of the tack in the heelseat, as just described a tack is inserted through the upper V-block 86into the rear end face of the last at a point at one side of the backseam and adjacent to the plane of the heel seat, as is also clearlyshown in Fig. 9. This tack and the lower tack previously driven arepreferably left with their heads upstanding from the surface of theupper to facilitate their subsequent Withdrawal. The upper rear tack issupplied by the separating mechanism 170 to the block 86 through a tube190 and is driven bya driver attached to the forward end of a driver bar192 which is actuated by a lever 194. The lever 194 is moved to the leftin Fig. 1 to tension a suitable driver spring located on the shaft 178by the action of a cam'196 upon an inward projection 195, Fig. 15, ofthe lever 194.

' is still held in that The cam 196 has its drop so located as to permit0pc ration of the driver bar 192 at a point later in the cycle of themachine than the cam 182 permits operation of the driver bar 174. I

For driving the rear heel seat tack a lever 200 is pivoted at 202 to thecarrier which advances. the wiper over the shoe bottom and is raised totension the driver spring by the action of a cam 204 located behind thecam 42 in Fig. 1 which acts upon a roll 206 on the lever 200 to raise adriver bar 208. The driver bar 208 is released to drive the heel seattack, as shown in Fig. 9, substan tially simultaneously with or slightlylater than the release of the driver bar 192 drive the upper rear tack,also shown in that figure. The rear heel seat tack is supplied to thewiper 70 by the separating mechanism 170 through a tube 210, Fig. 2, anddrops into a tack retaining means in the wiper 70 into position beneaththe driver on the bar 208, as shown in Fig. 7. The tack retaining meansin the wiper 70 has the construction shown in Figs. 10, and 11, andcomprises a member 212 having a funnelshaped slot 214 open on the innerside and having its wide end located beneath a passage in the wiper 70leading from the opening of the tube 210 to permit a tack to drop intoit. The member 212 has an outwardly extending stem 216 which passesthrough a member 220 and is retained by a pin 222. A spring 224 islocated in a socket in the member 220 and acts to press the member 212inwardly into tack retaining position but is adapted to yieldupon-descent of the driver to permit the tack to be driven past themember 212 and into the work. The member 220 is formed, as best shown inFig. 10, with a flange 226 which engages grooves 227 in a wiper member70 'to retain the member 220 in position.- The flange 226 is cut away onopposite sides so that by giving the member 220 a quarter turn it may beremoved from the wiper member 70 for inspection and clearance of thetack passage in case it should become clogged. To insure exact lo-'cation of the member 212 with the tack passages in the member 70 alocating pin 228 is provided which engages a hole/230 in the member 70when the member 212 is placed in operative position.

echanism is provided for inserting a plurality of tacks through theflange of the counter adjacent to the corners ofthe heel seat as isclearly shown in Fig. 16. These tacks plreferably and as shown do notpass throug the upper but through. the counter, lining and innersoleonly to secure the counter in against the rear portion of and servefirmly the last while it position by the pressure of the upper V-bIock86, by the counter corner and side clamping projections 154, 152,

described the tack proper position and by the wiper 70. These flan etacks are supplled by the separating mechanism 170 each of the guides254,256 is provided a tack pocket for holding the tack in position untilit is driven comprising two members 258, 259 which are pivoted togetherby links 260 to permit separation of their tack holding ends and arenormally held closed bya spring 262. Between the members 258, 259 isprovided a slot 264 and by separating the tack holding ends or jaws ofthe members 258, 259 these members may be placed in position to beretained upon the lower ends of either of the driver guides 156, 154which are each formed, as shown, at the right in Fig. 12. When themembers 258, 259 are allowed to close, the slot 254 embraces, forinstance, the portion 266 of the driver guide 254 and the jaw mem-,

bers are held from downward movement by a flange 268. When thuspositioned the tack pocket 270 formed in the inner ends of the members258, 259 is in alinement with the driver passage 272 in the driver guide256. The tack pocket 270 has a form half of which is illustrated in Fig.13 which is adapted to hold a tack in position beneath the driver untilits descent whereupon the two portions of the. tack pocket yieldlaterally to permit the passage of the driver through the pocket for theinsertion of the tack into the work. It will be observed that by theconstruction pockets are readily removable when necessary and forconvenience in initially separating the members 258, 259

the forward inner edges of the members are plete removal of them fromthe driver guide.

The flange tacks'are driven by drivers 276, 278 which are connected, asshown in Fig. 2, withma head 280 fixed upon the upper end of the driverbar 208 by which the central heel seat tack is driven. By thisconstruction, therefore, the flange tacks are driven simultaneously withthe central tack and by the same driver spring. It will be seen that, asshown in Fig. 1, the counter driver ides and drivers are locatedsomewhat in afvhnce of the central heel seat tack so that they passbeyond the portion of the margin of the upper which is laid over theheel seat by the wiper 70 and insert their tacks through the flange ofthe counter adjacent to the corners of the heel seat and beyond themargin of the upper. The position of the counter tacks is clearlyillustrated in Fig. 16. This figure shows also the position of the threeother tacks which are driven through the assembled upper.

. that a The counter tack driver uides are arranged for adjustmentlatera ly of the shoe to position the tacks at different pointslaterally of the flange of either wide or narrow shoes. guides 254, 256,Fig. 3, are supported on slotted brackets 255 by screws 257 which'passthrough the slots in the brackets and into the guides.
